First: Improve life and extend the use time of lamps. The overall life of the drive circuit, especially the key components such as: the life of the capacitor at high temperature directly affects the life of the power supply;
Second: Improve efficiency and improve the light effect of lamps. LED drivers should challenge higher conversion efficiency, especially when driving high-power LEDs, because all the power that is not used as light output is dissipated as heat, and the power conversion efficiency is too low, which affects the energy-saving effect of LEDs. ;
Third: reduce costs and improve purchaseability. At present, in the application of low power (1-5W), the proportion of the cost of the constant current drive power supply has been close to 1/3, which has been close to the cost of the light source, which has affected the market promotion to a certain extent.
